  • Therefore, when zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms diffuse with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with zinc and sinks into the bottom of the hot-dip galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • Razor blade barbed rope has been widely used in military sites, prisons, government agencies, banks in the world. The walls of living quarters, private homes, villas, fences, doors and Windows, highways, railway guardrail and border lines and other protection and security.

  • Large roll galvanized wire phosphating film is dark gray to black gray, the thickness is generally 5-20μm, has better corrosion resistance in the atmosphere. Membrane is a microporous structure, strong adsorption ability to paint, such as used as paint bottom, corrosion resistance can be further advanced. Metal oxidation treatment: Add steel products to NaOH and NaNO2 mixed solution, heating treatment, the surface can form a layer of thickness of about 0.5-1.5μm blue oxide film, in order to reach the purpose of steel corrosion prevention, this process is called blue treatment, referred to as blue.

  • For the wide use of screen, the state has regulations. You also specify the diameter size, mesh size, or usage method. For plastering nets, the mesh should be less than 20 and the diameter should be greater than 1 mm. Not only are specifications specified, but safety is preferred if wire mesh is used in exterior plastering nets. If you fall, the consequences are unimaginable. Therefore, the application of norms should be combined with reality.

  • Strength of galvanized wire: tensile strength is the great tensile stress that the material can withstand before tensile fracture; Yield strength has two indexes: upper yield and lower yield. It is a process in which the stress does not increase but the deformation continues to occur during the tensile process. When the force value drops for the first time, the major stress is the yield strength, and the yield strength must be less than the tensile strength.

  • 3. Put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and it is an important measure to stabilize the PH value in a numerical range. At the same time, it is convenient for the filter to filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

  • For example, if the barbed rope is used to circle, the cost per meter is only a few yuan, if the ring with other products, it may be more than ten yuan or even 20 yuan, which undoubtedly increases the cost of the user again, so the cattle and sheep with barbed rope is the most economical product

  • The screen is made into a box-like container, with stone filled with cages, can be used to protect and support seawall, hillside, road and bridge, reservoir and other civil engineering, flood control and flood resistance is a good material.

  • Small and medium-sized cat cages, dog cages and fences are mostly made of pure iron wire, wire diameter is generally between 2-5mm. Of course, the larger the cage, the thicker the wire, because the larger cage needs to withstand more force.

  • Nestor rolling cage, high-speed railway Nestor rolling cage and railway Nestor rolling cage are all produced, sold and installed in accordance with the technical requirements of the reference drawing of railway line 2012-8001. Nestor rolling cage is a kind of protective equipment emerging in railway in recent years. Nestor rolling cage is connected by Nestor connecting clip on the longitudinal tensile rib fixed on the bracket. The longitudinal tension and the support are connected with the Φ2.5mm cold-drawn galvanized steel wire around 2 laps and then tightened. The support is set in the column and the middle of the span of the protective fence of 3m. The other spans are only set with the upper column, and the support and the protective fence are connected with the bracket hoop. For the protective fence that has been installed with metal mesh, the Nestor roller cage is directly fixed on the transverse sheet and wire of the metal mesh with the cold-drawn galvanized steel wire of 2.5mm or the Nestor connection fastener.

  • So why sometimes the size of the bundle is the same, the price will be a little different? This is mainly due to the difference in weight. The lighter the bundle, the lower the price. This is the main factor leading to the relatively large price difference.

  • Plastic coated welding net: PVC plastic coated welding net is a kind of tall appearance of the welding net, plastic coated welding net picture upper protective barbed net, cable for galvanized steel wire, PVC coated plastic treatment, in the protection of beautiful at the same time, to ensure the strong and durable. Material: low carbon steel wire, PVC coated plastic manufacturing process: steel wire welding coated plastic, can also be separate plating, hot plating and coated plastic. PVC coated plastic welding net uses: industrial, agricultural, municipal, transportation and other industries fence, decoration, protection and other facilities.
